Every great relationship is built on two key components: love and honesty.
It may be a complicated relationship between the Philadelphia Eagles and their fan base, but there's no denying that the feelings are mutual, even when it doesn't look like it on the outside. Other NFL fan bases hate Eagles fans because they can be vulgar and seem to complain about the team even when they are winning.
That's because the city of Philadelphia understands football better than most people do, which makes it harder for "football analysts" to talk down to Eagles fans as if they don't know what's going on.
